Anyhow, I discovered that you can load the individual channels into WinJupos and do an "Image Measurement" on each of them, setting the time that they were taken, and then use the "Image Computation" to combine these and WinJupos will rotate them to all line up correctly.
WinJupos got it close, but not exactly right, so I followed it up by loading the RGB image into Astra Image, splitting the channels out and then recombining them with a couple of small alignment changes.
So here's the result of trying this out... as you see, this image has good alignment between the channels both at the edge and the centre.
cheers, Bird
